How can I resolve this iCloud Error?

Question

Hi I am trying to get my core data app syncing to iCloud so that multiple devices can be used.

I just started a new iCloud account for testing and installed my app on both devices. I have enabled my app for iCloud using instructions at this link Using CoreData with icloud and by also comparing my app to apple's coreDataRecipes example code.

I was not getting any syncing occurring so I did some logs to find out what was occurring. After adding an object to core data from iPad A i received the following log on iPad B which was connected to the computer.

2012-01-20 17:35:35.979 My-App[407:22d7] AppDelegate Merge Changes From iCloud Notifications
2012-01-20 17:35:35.980 My-App[407:22d7] AppDelegate managed Object Context

2012-01-20 17:35:35.981 My-App[407:707] AppDelegate Merge icloud changes for context

Then I get this error

, the baseline will not be adopted.

It would be greatly appreciated if someone could let me know why I am getting a conflict due to the (null) values and where I can look to resolve this.

Thanks

ps. I have changed the seen in the log app name, unique identifier and company name just for this post.

EDIT Syncing is occurring however it seems to be delayed.

Answer 1

@coder007 I submitted a question to apple about this. They wrote back and said that I should submit a bug report and they credited my question back to me. To be honest I haven't yet had the time submit the bug report, so if you can then it may be the way to go. It must be a problem with iCloud that needs ironing out

Update

I Don't have this error anymore, I think apple is gradually improving and eliminating issues with iCloud. I don't think it is a problem on the developers end in terms of coding from my perspective.
